Is Pinterest the next Facebook?

Ben Silbermann can’t stop staring at the refrigerators. The Pinterest co-founder and CEO and I are standing in the break room of his company’s garage-size Palo Alto office. He’s just flown back from Austin’s SXSW interactive festival, and a redesign of his website is two days away. It’s all a little overwhelming. But at this moment his full attention is focused on three glowing refrigerators. Sometime during his brief absence, a service has delivered them fully stocked and branded with the company logo. They’re wedged into the tiny backroom behind the foosball table that three employees — roughly 15% of his workforce — are using for a conference. “I’ve been gone for one day, and it’s so upscale,” he says. “We used to just run to Costco all the time.”
